A building, structure or part thereof for which construction has begun prior to a change in regulations, which change would make the structure once completed a nonconforming structure, may be completed in accordance with the approved permit and plans, provided the work is implemented continuously and without delay. Such structure shall be deemed to be a previously conforming structure and shall thereafter be subject to the regulations set forth herein. (Ord. 3153 § 2 (Exh. A), 2010).
